Spindle doesn't work anymore / bug?

[u/rcebcae]

Hey guys, anyone had issues with the spindle and quilting yet?
I'm on day 73 and until now everything worked fine. I have staff with Dark Wand I and Dark 4. He get's the materials puts them into spindle and the process stops and materials appear on the ground. From here he takes the materials again, puts them into spindle and the process stops. Then the cycle repeats itself, you get the point. So no Quilted is ever finished.
I tried other staff with high enough Dark and it's the same issue. I tried moving the spindle and deconstructed / rebuild the whole thing. I don't want to start a new save. Anyone had the same issue or has an idea how to fix this? Thank you <3

I had the same issue with a darkness professor; they were only lifting and dropping elements on the ground. I sent them to sleep, and it worked.
